Gene Rv2069
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in promoter recognition, transcription initiation. |
| Product | RNA polymerase sigma factor, ECF subfamily, SigC |
| Comments | Rv2069, (MTCY49.08), len: 185 aa. SigC, RNA polymerase sigma factor, ECF subfamily (see Gomez et al., 1997; Chen et al., 2000), similar to many. |
| Functional category | Information pathways |
| Proteomics | Identified by mass spectrometry in whole cell lysates of M. tuberculosis H37Rv but not the culture filtrate or membrane protein fraction (See de Souza et al., 2011). |
| Transcriptomics | mRNA identified by real-time quantitative RT-PCR during exponential growing cultures. mRNA level decreased under stress conditions (0.05% SDS) and after heat shock (see Manganelli et al., 1999). mRNA also identified by DNA microarray analysis and possibly down-regulated by hspR|Rv0353 and hrcA|Rv2374c (see Stewart et al., 2002). |
| Mutant | Non-essential gene for in vitro growth of H37Rv in a MtbYM rich medium, by Himar1 transposon mutagenesis (see Minato et al. 2019). Non-essential gene for in vitro growth of H37Rv, by analysis of saturated Himar1 transposon libraries (see DeJesus et al. 2017). Non essential gene by Himar1 transposon mutagenesis in H37Rv and CDC1551 strains (see Sassetti et al., 2003 and Lamichhane et al., 2003). Non-essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011). M. tuberculosis CDC1551 sigC|Rv2069 mutant growth is comparable to wild-type in murine J774A.1 alveolar and bone marrow-derived macrophages; mutant has no growth defect in DBA/2 mice but pathology is reduced and death is delayed (See Sun et al., 2004).
